I finally had a chance to try playing a character who contracted vampirism, and I used the following mods which enhance this a bit:

There were some fun new abilities, and I liked how you can reverse the vampire progression with Better Vampires, so you are stronger when you feed a lot.

However, it seemed rather strange to use health potions as a vampire. There is an option in Better Vampires to make it so you don't gain health from potions, but I play on Master difficulty with ASIS and the Deadly Combat mod, so it is almost impossible to survive without drinking every health potion you find.

Another possibility is to configure Better Vampires so that you can collect and save vials of blood from your victims, but constantly drinking vials of blood does not seem to be an ideal solution either.

What I would like to do is either make a mod (or find one if it already exists), that replaces the health/stamina/magicka potion management gameplay with feedings that give a temporary boost to your health/stamina/magicka bars. Ideally, instead of drinking lots of potions, you would need to feed a lot beforehand to survive tough battles.

Any suggestions, or perhaps an alternative idea to replace potions?
