While I've never had the luxury of any leftovers from my scallop dinners, if I did, I'd probably just LIGHTLY bind them with a LITTLE mayo & any favorite seasonings & take them with either some separate bread & greens to make a sandwich, or just separate greens to make a salad.
Dice, or coarse chop, add with some diced cucumber, a little red onion, mint, lime, little bit of curry powder, plain yogurt, a lil mayo, and use iceberg lettuce to make some refreshing wraps.
