2 4-mana creatures, 1 5-mana creature, and 2 5-mana vehicles. Granted, vampires are small and wide, but are there some other cards that i could add here? Bellowing Aegisaur is in the deck, for the moment, but it's only particularly useful if I can trigger Enrage.

I've supplemented the vampires with a lot of removal and combat tricks.  Try to trim that down to removal for large creatures + plus enough combat tricks that I can punish my opponenets for blocking.
