Cut chicken wings into three sections; discard wing tips. In a large resealable plastic bag, combine the soy sauce, orange juice and garlic powder; add wings. Seal bag and turn to coat. Refrigerate overnight. Drain and discard marinade. Place chicken wings in a greased foil-lined 15-in. x 10-in. x 1-in. baking pan. Bake at 350° for 1 hour or until juices run clear and glaze is set, turning twice.
