Hard to do the conversion without knowing what the exact serving size is of your protein or how many grams of protein there are per serving. That being said, most protein powders (if it's just straight whey protein and nothing too fancy) have a serving size of about 1/3 cup. There are 16 Tablespoons per cup, so you're looking at 5.3 Tablespoons to equal a one "scoop" serving.
A common amount of protein per serving is usually around 20 grams, so running the math, you're looking at 20 / 5.3 = 3.77 grams of protein per Tablespoon.
