Line a cutting board with plastic wrap and place 1 pork chop on top. Cover with another piece of plastic wrap. Pound the meat with a meat mallet or rolling pin, until ¼" to ⅛" thick. Transfer the meat to a plate, and repeat with the remaining pork chops, reusing the plastic wrap if possible.
Take out 3 shallow bowls or baking dishes. Place the flour in 1 dish; the egg, garlic powder, and salt in another; and the panko in the last dish. Beat the egg with a fork until well combined.
In a large, high-sided skillet over medium-high heat, heat about ¼" of vegetable oil.
Meanwhile, working with 1 cutlet at a time, coat the pork in flour, then in egg, and finally in the panko. Use your fingers to press the cutlet into the breadcrumbs.
Once the oil is shimmering, transfer 1 cutlet into the hot oil and fry for about 2 minutes on each side until golden brown. Reduce the heat if the cutlets are browning too quickly or unevenly. Transfer the cutlet to a plate lined with paper towels. Adding more oil as necessary, continuing frying all the cutlets.
Serve with lemon wedges.
