In a large nonreactive bowl, combine the mayonnaise, lemon juice, salt, Worcestershire sauce, hot sauce, garlic powder, celery salt, dry mustard, pepper and paprika; mix well. Add chicken pieces and toss to coat.
Cover and refrigerate for at least 4 hours (or up to 24 hours, if you plan ahead).
After marinating, remove chicken from the refrigerator and toss around in the mixture once again (to make sure pieces are well-coated).
Preheat oven to 350 degrees Fahrenheit.
Place crushed corn flakes and parsley in a shallow dish; mix well.
Roll chicken pieces in corn flake crumb mixture to coat. Place in a single layer in a large baking pan.
Bake uncovered at 350 degrees Fahrenheit for about 45 to 55 minutes, depending on the size pieces you are using, turning gently halfway through or until done.
