Normally at the point you are zoned out it is too late to do much besides last hit under your tower. Because they are ranged, they can continue to harass even as you pick up those last-hits.
At that point my preferred method (without jungler help) is to back away (recall) if they are zoning me away from me turret. Buy some items and if you are not too far behind you can take the advantage. In particular and if things are very dire, buy a fortitude elixir!
I think a key point here is that against ranged champions, melee have an advantage once they get within melee range. So you really just have to pick and choose your battles and ensure you win the early exchanges as taking too much harass will just snowball the lane against you.
Remember good match ups are key so always consider that in champion select if you are running draft mode!
If your top was hard counterpicked, my suggestion would be:
* Get a HARD leash on your first buff camp (strong enough that you keep Smite
but still gain a Level); Start with the one furthest from your Top lane
(Red Buff if you're on Blue Team, Blue if you're on Purple)
* Immediately RUSH to your next buff and kill it with Smite. Make sure you use
your Pots and are at 3/4 HP or better!
* Immediately RUSH to top lane to gank. You will be at Level 3,
and if you are a fast enough jungler, the top lane will be just about to
ding Level 2. A gank this early is usually devastating. If you can wrangle
it so your Top Laner gets the kill, the gank was perfectly successful.
After all of that, have your Top Laner stick close to turret and ward his Tribrush and right in front of the Baron pit. This will give enough time to evade possible ganks, and the farming in front of tower leaves the other Teams' Top wide open for ganks.
Gank top about 150% more often than you normally would. This is known as "Camping a lane".
Allow your Top Laner to take your wolves (if on Blue Side) or Small Golems (if on Purple) to get some EXP advantage over the other team Pre-Lane. Help him out with them so he doesn't take too much damage, but make sure he gets the EXP! This provides about 1/2 the EXP required to reach Lv. 2.
Make sure to stress to him how important it is to passively farm WHENEVER possible in lane; Then, when you gank, that he needs to let you initiate but STILL NEEDS TO SMACK THEM IN THE FACE A FEW TIMES! Remind them that even though they got counterpicked, if they get themselves fed (with your help), they basically become uncountered again.
If your Top Laner is unresponsive or unhelpful after these tips and suggestions, then let him be and help your Carry Lanes get fed. Play around him strategically and you can still pull off a win. If the Enemy Top Lane is fed, but the rest of YOUR team is fed, you still can win.
Do your best to give your Mid Champ the Blue buff whenever it comes back up, and to deny the other Mid the chance to get THEIR Blue! If you force the other jungler to smite-steal it, then you did good. (This may not seem like it would help out Top at all, but trust me: getting Mid any sort of advantage over their lane means that they can start roaming and help out Top and Bot sooner, which means more help for you and an easier chance at winning the mid game.)
ALso, ALWAYS REMEMBER: Prioritize Towers and Map Objectives over Kills.
One Tower = 150 Gold per Champion. This equates to 750 Gold for the team. That's more gold than a Legendary Kill streak ending! one or two champions dying for a tower is okay, but not optimal.
Dragon = 190 Gold per Champion, PLUS Last-Hit gold (40 gold) AND global EXP for the team. 1,000 gold total if a Masteried Smite was used. If a tower goes down mid-fight, you still come out on top.
And finally - do your utmost to make sure the kills from your ganks are spread around as much as possible amongst your team members. Share the wealth! You want everyone a little fed, not one or two a lot fed. (A little secret: Supports may not be supposed to get kills, but a fed Support (2-4 kills by late game) is a SCARY thing indeed!)
Hope this helps!

Yorick actually has very little means of escaping, so if he is ganked from early on he can be gimped enough to the point where he is not a large threat. He becomes incredibly tanky, so make sure you try to get him early. The later you gank him, the more levels in Omen of Famine he'll have and be much tankier. Once he's level 3 he also will be able to throw up all 3 ghouls for 15% damage reduction making him very tanky. Many champions can lane against him by farming his ghouls. They give no gold, but Tryndamere and Nasus scale better into late game and give them means of gaining strength in lane. Tryndamere gets it by hitting the ghouls for rage buildup and actually end up healing off of his skills from lifesteal and Bloodlust. Nasus gets power by building Siphoning Strike charges off of the ghouls.
