I use [http://www.nexusmods.com/skyrim/mods/15524/? Amazing Follower Tweaks] that lets you turn followers into a vampire (or werewolf), other vampire overhauls let you turn people like [http://www.nexusmods.com/skyrim/mods/9717/? Better Vampires] but would conflict with the one you already have. There is a command for Lydia as it's different for each race open the console click on her and use -

setrace nordracevampire

If your trying to get around the mod making The Gift quest uncompleteable i'm not sure it'll work though, you might need to skip past the bite with the command -

setstage DLC1RV06 100

I would think the spell and bite is what progresses the quest stage.
