You need to determine a few things BEFORE you even get locked on to. Read the briefing and see what targets could return fire. 
for Missiles:
MAD-4 stay the fuck away from these. If your high, your fucked. These will pitbull on you.
SAM generally easier to defeat, high g's work rather well but you loose a lot of energy. Some come with pitbull but most don't
MANPAD throttle down and flare
SAAW dont be high with these guys, get low and terrain mask
A to A high g, notch, terrain, chafe
Sea SAM its a sam on a boat
Sea IR its just like a manpad on a boat

Once you destroy radars, you have the option to stay high and above any IR threats. as for general techniques for missile avoidance. you want to fly perpendicular to the oncoming missile to drain its energy(beaming), then if its still get close enough push it in a direction and do a high g move. 
tldr
id threat, choose best avoidance, execute.
