Next leg would be MNL - SIN - MLE with SQ -J, it will cost 60K SQ miles transfer from UR/MR

from MLE you can come back with EY-J MLE-AUH-LAX, it will cost 135K AA miles, you are short on AA, you can either top off or transfer SPG

You can also do these in reverse.

Good luck! I would not recommend using any of your miles for Y seats
