Possibly a bad motor mount or transmission mount.

More likely your driveshaft slip-joint needs to be lubricated; as you go from Park or Drive to Reverse, the axle winds in the opposite direction and the slip-joint needs to slide. If it's sticky, it resists then lets go suddenly causing the Thump noise.
