In a wide shallow bowl, combine the panko bread crumbs, plain bread crumbs, garlic powder, Italian seasoning, black pepper, and salt. Put the flour in a second bowl and the beaten eggs in a third bowl.
Coat the cheese sticks halves in flour, then in the beaten eggs, and finally in the breadcrumbs mixture. Coat with the eggs and breadcrumbs a second time.
Place in a parchment-lined pan and freeze for at least 2 hours.
Heat oil in a deep fryer (or use a large pot with a thermometer) to 350˚F. Remove the cheese sticks from the freezer and deep fry them 5-6 at a time for 2 minutes until golden brown.
Drain on paper towels and serve with marinara sauce.
