In a medium bowl, mix crab meat, cream cheese, Worcestershire sauce, sugar, green onion and garlic powder. Stir until the mixture is well blended and creamy.
Lay a wonton wrapper flat on a clean work surface. Spoon about 1 tablespoon of the filling into the center of the wrapper.
Lightly moisten the edges of the wonton wrapper with water. Fold and seal according to your preferred method, pressing firmly to remove air and full seal the edges.
Place the filled wontons on a baking sheet or plate and cover with a damp paper towel. Keep both filled and unfilled wrappers covered while assembling to prevent drying out.
Pour 2-3 inches of oil (about 3-4 cups), depending on pan size) into a deep skillet or saucepan. Heat oil in a deep skillet or fryer to 350℉.
Fry the wontons in small batches for 2-3 minutes, turning as needed, until golden brown and crisp.
Remove with a slotted spoon and drain briefly on paper towels. Serve warm with your favorite dipping sauce.
