Place the beef cutlets between two sheets of plastic wrap and pound to an even 1/8-inch thickness.
Season both sides of the beef with salt and pepper.
Place the flour in a shallow dish. In a second dish, whisk together the eggs and milk. In a third dish, mix the breadcrumbs with garlic powder and paprika.
Dredge each cutlet in flour, then dip into the egg mixture, and finally coat with the breadcrumb mixture. Press to adhere.
Heat about 1/4 inch of vegetable oil in a large skillet over medium heat until shimmering.
Fry the breaded cutlets for 2-3 minutes per side, or until golden brown and cooked through.
Transfer to a paper towel-lined plate to drain excess oil.
Serve hot with lemon wedges if desired.
