Honestly, I think crate training is the most effective method. MOST dogs won't potty in the place where they sleep, so he should have just enough room to stand up and move around comfortably. Like you are doing, if you can't watch him 100%, put him in his crate. The very second he comes out, take him to his pad until he goes to the bathroom. If he doesn't go, then he needs to go back into his crate for another 10-15 minutes and continue until he goes. At night he should be crated and when you are gone, he should be crated. It's tough to put them in there, but this is the method that I have found to be most useful.

When you are watching him and you see him going somewhere else, just a firm "NO" and then pick him up and put him on his pad. Tell him, "This is where you POTTY" emphasizing the "potty" because you want him to learn that word. When he does pee on his pad, make sure you give him lots and lots of praise and a treat.
