Preheat oil to 370 degrees F (185 degrees C) in a deep fryer, deep frying pan, or pot.
Coat squid with garlic powder, onion powder, salt, oregano, basil, parsley, paprika, cayenne, and white pepper in a medium bowl. Mix thoroughly. Add flour and toss to dredge.
Fry squid in the hot oil, in batches if needed, until light brown, 2 to 3 minutes. Do not overcook, or squid will be tough and chewy. Drain on paper towels. Serve with lemon wedges and marinara sauce.
