Welcome to FT!
As has been mentioned, there's a limited amount of help that we can give you because availability of award seats, and their release date, is a bit of a black art. Short of the (somewhat obvious) advice that you should start looking ca 330 days out, and then on a regular basis, there's not much we can do.
The best is to have a few destinations in mind, and the carriers that will get you there, and then check availability on a regular basis. A bit like buying a house in a desirable neighbourhood, when something comes up, you need to be prepared to pull the trigger instantly.
