Preheat oven to 350°F Lightly grease a baking dish.
Blend mustard with honey. Brush the chicken breast halves on all sides with the honey mustard. Stir the bread crumbs, parmesan and garlic powder together in a shallow dish. Press the chicken into the bread crumbs to evenly coat. Arrange the chicken breasts in the prepared baking dish.
In a bowl, mix the butter, lemon juice, and water. Drizzle about 1 tablespoon of the mixture over each chicken breast. Pour the remaining mixture around the breasts in the dish.
Cover, and bake 45 minutes in the preheated oven. Uncover, season with paprika, and continue baking 15 minutes.
