What would be good quest to do as a Vampire or Dawnguard that are not part of the expansion? With Skyrim being as big as it is its easy to miss quest, so my next character is going to be a vampire mage and I was thinking about doing these so far:

College of Winterhold Quests
Boethiah's Calling - seems like something every evil charter should do plus the armour.
A Daedra's Best Friend - could be good for both vamp and dawnguard
Falion's Secret
Dark Ancestor
Lifting the Shroud
Laid to Rest - probably more of a dawnguard quest
Ill Met By Moonlight - both
Waking Nightmare
The House of Horrors
The Taste of Death
Coated in Blood
The Mind of Madness
The Man Who Cried Wolf
The Wolf Queen Awakened
Kill the Vampire - dawnguard unless there can only be one
A Night To Remember
The Whispering Door - good weapon for a vampire warrior
Dark Brotherhood - if it fits your character
Then of course the quest that come with Dawnguard

That's about all of the quest that I can remember that might go well with a vampire or dawnguard based character, please feel free to add any quest I missed or you think would go well with a vampire or dawnguard character.

I am going to make a character just so i can get the VL form early and then do all of the quests using it. DB, TG, CoW, Comp, MQ, and CW

I might do that but it depends if destruction and conjuration skills increases while in vampire lord form.

You might not be able to complete the Companions Guild, unless you're willing to give up your Vamp Lord form.

Ah true...hmm maybe i will get that out of the way 1st

I'm going to complete the companions, but then just cure being a werewolf as it doesn't offer an awful lot of perks at the moment.

I forgot about Shriekwind Bastion, which is not too far from Falkreath but is probably more suitable for a vampire hunter. I imagine if you are part of the dawnguard there are probably lots of side quest to hunt these vamps. This link has all the known vampires in Skyrim or close to it:
