Finish off the Ptolies, get Palmyra and maybe you can try to invade the Indus valley, really rich cities found there.Maybe finish off a few other eastern enemies, but watch out for the Saka.
Capturing the Aegean can also bring a lot of wealth but I dont think you want to betray your faithful Mak allies. And last but not least, you will have to conquer the Hayasdan sooner or later.
