to become a vampire you need to wait upon a crescent moon which after a full moon you need to wait 4 days roughly for the crescent moon to appear, at this time every night you will find a vampire somewhere west of riften called a "bloodfiend" this blood fiend will allow you to contract the disease and become a vampire, after getting this disease if you head south of riften outside you will find a hooded man waiting at a lamp post that will give you the quest to get your powers
