Wood elves: if you walk from Volunruud towards the Shrine of Mehrunes Dagon, you´ll find a bloody trail - following the trail leads you to two dead wood elves where the other one has a treasure map, too.

Falmers: one of the easiest falmer kills would be at the beginning of Shimmermist Cave after the entrance where you have to kill one spider only. Follow the cave deeper in and there´s a falmer on a "balcony" (beware the trap), very easy to sneak kill. Kill, turn back and exit (I usually don´t clear the cave because it may be given as a part of the Companion´s questline later on).

The rest of the bloods are usually found (as said above) from Halted Stream Camp or from Liar´s Retreat (as a bonus though, Liar´s Retreat gives you unique weapon and Tarvern Clothes) :)
