I was thinking of working on vampires on my server... but there are challenges I see coming.  Some of the thoughts I have had might help you though, or might not.

Gaseous Form would simply be a polymorph spell for a new type of polymorph.  I would give the new form damage reduction +1/10, a str of a 10 a slam attack that would do no damage.  I would also consider giving it the ability to cast a sanctuary type spell unlimited times a day.  I think this could take away the ability to harm others and or be harmed.

for my own server I was considering making a coffin placeable that would allow a vampire to have conversation with it.  one option to take the vampire to a separate area named inside coffin where he could wait out the sun, another option so the vampire could pick up (destroy placeable and put a 150 pound coffin in his inventory.  the coffin would have a unique power that would allow the vampire to put it down.  (create placeable.)

then when the vampire respawns change his respawn option to take gaseous form.  then run the script in that so that he polymorphs into gas but has no option to unpolymorph.  allow the unpolymorph to only when he is inside coffin.

just a thought though....
