In a bowl, mix the cream cheese, crab meat, green onions, garlic powder, and soy sauce until smooth.
Lay wonton wrappers on a clean surface. Add 1 tsp of filling in the center of each.
Brush the edges with water and fold into a triangle or pinch into a pouch shape. Press tightly to seal.
Place filled wontons on a tray and chill in the fridge for 10 minutes.
Heat oil in a skillet to 350°F (175°C). Fry 4-5 wontons at a time, about 1 minute per side, until golden.
Drain on paper towels. Serve warm with sweet chili sauce or soy dipping sauce.
