So I'm running into some complications over the Vampire class. I recommend going fully monk focusing on Stone Fist for both build and tradition. Also, 1st level characters are unable to learn supernal so you can go with Primordial. Also: as a revenant you can only choose your background race (tiefling like you said) which would prevent bloodline features (such as vampirism) from transferring over into the new revenant form. So in your back story, you can say that you were a vampire but your character will only be allowed to use revenant features revenant and tiefling wise.

There are some good features from the revenant race that do extra damage types. The feat Chill of the Grave will turn your Dark Reaping's type into cold and nectrotic damage. The Death's blessing feat will fully make you dead, meaning that suffocation doesn't affect you (which would mean you no longer need to breath, and so you can be immune to suffocating toxins, drowning, etc.). Empowered reaping does bonus damage points with your Dark Reaping. You initially get +2 bonus, level 11 it increases to +4, and level 21 increases it to +6.

Your powers would also be monk powers if you decide to stick with that class. Sorry I don't have the Heroes of Shadow book.
