In the 3.5e we had the level adjustment, but I didn't find it or any rule talking about it, on the 5e.
How can I create a Vampire or a Lycanthrope or a Half-Dragon? There is a mention about "as player" but there is no restriction or "how to" to make my own character.
The Bullywugs are from this image from Monster Manual 2, page 29. I found it on the web with descriptive data on Wikia:
Having played the encounter, I believe the correct mapping of types, from left to right is:
The frog head token is Sporeback Frog from Monster Manual 3, page 91 - though in the module it's meant to represent the "Giant Frog".
[UPDATE:] Added the details from the comments, especially @Ravn. Thanks to everyone for the pointers and be sure to vote-up Ravn's comments...
Start with vampire spawn stats instead of vampire. This has a CR of 5, so it's perfect as part of an encounter with your party if they're already low on resources from the traps, etc. Add in the shape change and Misty form traits from the vampire, which makes it harder to kill, but not harder to fight. Done.

There are two options here:
Create a template (or use one of the templates provided by the monster manual). For Vampires it's outlined on pg 295, for Lycanthropes it's outlined on pg 207, half dragon is outlined on pg 180.
Use the custom race construction rules on dmg pg 285-287.
These provide the by the book rules for these possibilities. There is no LA in 5e.
