In a large bowl, mix together crab meat, cream cheese, scallions, Worcestershire sauce, garlic powder, salt, and black pepper.
On your working surface, lay a wonton wrapper. Place about a tablespoon or less of crab filling in the center. Brush the whole border with very little water. Bring the opposite ends together and pinch to seal tight. Make sure to push any excess air out to prevent them from popping when frying. Repeat until all the crab filling is done. Make sure to cover the wonton wrappers and rangoons with a towel or place in a ziploc bag to prevent them from drying out while you fill and seal them all.
In a pot, add oil high enough to cover the wontons when dropped in. Heat over medium-high and let it reach right below frying temperature (325 to 350°F). Do not exceed this temperature or they'll fry too fast and burn.
Drop the wontons in, making sure not to overcrowd them. Fry in batches. Once they are golden, take out of the oil and transfer to plate with a paper towel to drain any excess oil.
Serve with sweet chili sauce or sweet and sour sauce and enjoy!
