I pull back the wheel as far as possible, then slant the wheel towards the non drive chainstay(but not so much that the tire touches). I then tighten the non drive nut all the way down. After that, I push the back of the wheel so that it is centered, and tighten the drive side nut.

After doing this way for a while, I have learned how far off center I need the wheel to be when only one nut is tightened, to make it perfect in the end.
