I am wondering how a single-classed druid would go about casting Reincarnate on herself after she has died (if such is even possible)?

Some spells have a target or targets. You cast these spells on creatures or objects, as defined by the spell itself. You must be able to see or touch the target, and you must specifically choose that target. You do not have to select your target until you finish casting the spell.
You cannot see the target therefore they cannot be targeted by the spell using sight. If the player was within 5 feet, they could try to touch the target.
To explain why this touch will cause an AOO and why normal touch spells do not provoke attacks of opportunity:
Touch Attacks: Touching an opponent with a touch spell is considered to be an armed attack and therefore does not provoke attacks of opportunity.
The spell in question is not a touch spell, so you are not normally considered to be armed (Unless you have a natural weapon or improved unarmed strike)
Although, if it was just normal invisibility, actually taking that AOO would break the spell, which is also useful.
The caster of magic fang typically can pick only a natural weapon that the subject already possesses to be affected by the spell…
What usually dictates whether a creature is or isn't a valid subject for a spell is a spell's Target entry (see Magic on Aiming a Spell on Target or Targets for details). The spell magic fang has the entry Target: Living creature touched, but, upon casting the spell and subsequently touching the target, the caster picks "one natural weapon or unarmed strike of the subject [to receive] a +1 enhancement bonus on attack and damage rolls" (emphasis mine). Picking something that a creature doesn't have as the subject of an effect usually causes the effect to fail.
Thus I suspect that most GMs will rule that, while the spell's Target entry does mandate only that the subject be a living creature the caster touches, the spell's description increases the specificity of that Target entry to include "one natural weapon or unarmed strike of the subject," and if the subject does not possesses the natural weapon when the spell is cast, the spell fails.
…But this GM would likely let it slide anyway
However, the magic fang spell's Target entry is sufficient for this GM to rule that the spell doesn't outright fail if the caster picks a natural weapon the subject doesn't have to gain the spell's effect. Instead, this GM would rule that until the creature gains the picked natural weapon the subject's magic fang spell effect is present but, essentially, dormant, its duration counting down normally. This GM's ruling is—perhaps excessively—permissive, though. That is, if this GM can find any reading of a spell that allows a spell to work instead of to fail outright, this GM usually gravitates toward the reading that allows the spell to work. But were a GM to rule that spell magic fang functions in the traditional fashion—capable of affecting only an existing natural weapon—this player wouldn't flip the table and leave the campaign .

Check this out. Have a magic item forged that casts this spell on you when you use it. That should just about cover everything you need.
Have a wizard forge a magical item for you. He'll cast Contingency and you'll cast Reincarnate. From there, it's just a standard Craft check.
EDIT: There is one tiny thing I overlooked. In Pathfinder, Contingency can only be cast once until the conditions are met, and the Contingency is expended. Depends on your DM, but if he likes, he could reasonably enforce that the wizard can't cast Contingency again until the item is used or destroyed. Something to think about.
EDIT 2: @Molot has provided a fairly simple solution to the Contingency issue.
I don't think it would work as easy as Molot says, since the spell restriction itself says:
This means that using the scroll would still impose the Contingency restriction on the caster, even if they aren't even a wizard and are UMD'ing it, as far as I can tell. Still, if you can find someone else willing to do it for you, you're good, or even if the Druid can make the item himself like he also suggested.
Although, this all kind of hinges on how your DM interprets "dispels" in this context. If they think that the magic is tied to the item completely, then so be it, it stays once the wizard casts Contingency elsewhere. But it seems like it would also be reasonable for him to say that the ring loses its effect if the caster uses Contingency elsewhere, or perhaps until the other Contingency is resolved. I don't really know how I'd handle it personally as a DM.
