Being blunt, probably only Turkey these days.. you have to do an OCC course, LPC, Training as required before you can even operate One flight, If you are willing to pay the airline the 10K or so it costs to do that...
You could do a couple of sims and then base training, but I doubt that would improve the CV, in other words a waste of money. There are jobs out there for experienced guys, but at 56 Asia is probably out unless you are current, I would look in Europe, but..767? not much, you could try Air Astana in KZ, they may bond you for the training, or Air Baltic on the 757, recency does not seem to be an issue with them
