I am in the process of putting in a new landscape. What can I do to amend the clay soil?

About 10 years ago we planted Amur maple shrubs along the back fence in our yard for privacy. Not quite sure what to do with them now, all the foliage, is at the top and they no longer provide any privacy. Also, they have a lot of dead wood. How do we prune them to give us privacy or should we replace them with some kind of evergreen shrub?
