Preheat oven to 400 degrees. Sprinkle chicken pieces with salt, pepper and garlic powder. Place pieces in a shallow baking pan with skin side down. Combine remaining ingredients, except lemon slices and pour over chicken. Bake, uncovered, for 20 minutes. Turn chicken and baste with pan drippings. Bake for 30-40 minutes more, until chicken is tender. Serve on a platter, garnished with lemon slices. This is also great cold!!
