Ghostwind said:Lords of the Night - Bottled Imp Games
Fang & Fury - Green Ronin
Out for Blood - Bastion Press
All three are excellent sources and actually complement each other well. Use all three and your players will tremble in fear at the very mention of the word 'vampire'.

The Green Ronin book is good if you want a PC Vampire race. The Bastion Press book is very good if you want a general book on vampires.
