Opportunities on the 767/757 are rare. Realistically you'll only qualify for a job in your present aircraft type due the the currency requirements of most overseas jobs. The exceptions to this are some of the bigger airlines that will hire you onto another type.

Age might be an issue. Many places will not hire beyond age 56/58/60 or some other arbitrary number.

You can register with the contract agencies and/or look at their website for jobs available. PARC and WASINC are two of the bigger ones for Asia contracts.

On your type the companies that come to mind are:

Ethiopian
SF Express
Hainan
Air Astana

possibles would include

Qatar and the new Singapore LCC
