In a large mixing bowl, combine flour, cornstarch, baking powder, salt, sugar, baking soda, onion powder, and garlic powder. Whisk together to blend well.
Slowly add the cold club soda to the dry ingredients while continuously whisking to create a smooth batter.
Let the batter sit for a few minutes to thicken slightly.
Dip your choice of seafood or chicken into the batter, ensuring each piece is well coated.
Fry the coated pieces in hot oil (350°F or 175°C) until golden brown and crispy, usually about 3-4 minutes per side.
Drain on paper towels and serve hot.
