In a medium bowl, combine the shredded ham, shredded cheddar cheese, mayonnaise, ketchup, garlic powder, onion powder, and Worcestershire sauce. Mix until well combined.
Spread the mixture on one slice of bread, top with the remaining slice of bread. Cut the sandwich in half diagonally.
Place the sandwich halves on a baking sheet lined with parchment paper. Place a slice of Cheddar cheese and a slice of ham on each half of the sandwich, overlapping the edges slightly.
Bake in the preheated oven for 12-15 minutes, or until the cheese is melted and the ham is crispy.
Serve the sandwiches hot.
