Here's a method I recently read. When the dog is approaching you on his own, use the command you want him to learn such as "Come" or "Here." The dog is then supposed to learn the command/behavior through that.
It makes sense when you think about many of the "tricks" dolphins perform. They are trained by taking a behavior they naturally perform and working with that.
I don't know if a dog's mind works in the same way.
I'm trying it...I'll try most anything until I find something that works.
