So what would happen
Traditionally (a.k.a. NOT in the Twilight universe) a vampire would NEVER bite a werewolf. Reason #1 -- They HATE them and would instead prefer killing them with silver stabbing weapons: swords, spears, arrows, etc. Reason #2 -- Lycan blood is repulsive to a vampire; they wouldn't bite them because it'd taste nasty.
If you are talking about twilight, the werewolf would die. Vampire venom is very poisonouis to werewolves (in twilight the book).
The werewolf would either cahnge completly vampire or just half, depending on their strength.
In twilight the werewolf would die .. Vampire venom is poisonous to werewolfs
