Are you clicker training? I've heard that works very well for hounds (most dogs actually). If you were clicker training you would not have to wait for her to do the whole thing before giving her a treat. What you do is try and get him to paw at your hand. Move it around like you want her to play with it or put a treat in your closed fist and wait until she paws at it. As soon as she does click and treat. Slowly raise your hand up after every few times she paws and you click and treat. Eventually you'll shape it to the point where you can hold your hand at a normal height then start opening the palm without the treat in it and when she touches it click and treat. You don't have to use clicker training but this is called shaping which is usually done with clicker training.
With my dog we did something called molding, we would say paw, pick up his paw then give a treat and put down the paw, then repeat. The thing with molding is that dogs don't think while they are doing it, you're basically doing it all for them they take a while to realize they actually have to do something not just wait for you to do it. So shaping works well in getting them to use their own brains and figure things out faster.
Don't get discouraged and think your hound can't learn tricks, he can you just have to persistent and creative! Always think about what steps you can take to get to the behavior instead of trying to go all the way on the first try, then try and figure out what you can do to encourage him to do that first small step.
