Unwrap the cream cheese from the package, and set it on a microwave-safe plate, for 15 seconds on high. In a medium bowl, beat cream cheese until light and fluffy.
Stir in crab meat, green onions, soy sauce, powdered sugar, and garlic powder.
Place the wrapper on a flat surface. Place 1 rounded teaspoon of crab mixture in the center. Put egg wash on the wrapper's edges. Lift one corner of the wrapper and pinch it together with the opposite corner. Repeat with the other 2 corners, so it forms an “X” shape (More detailed instructions are in the article above). Repeat with remaining wrappers and filling.
Heat 2 inches of oil in a wok to 350-degree F. Don't crowd wontons, just add a few at a time. Fry on one side for 2 min or until golden, turn and fry for 2 min or until the second side is golden. Then drain them on paper towels with a slotted spoon.
Serve immediately with dipping sauce.
