Actual tactics vary immensely according to the aircraft involved and what weapons they are carrying but the maneuvers are essentially the same. In WW1 they only had machine guys for dogfights, and so you had to close to within 400 yards or so for the guns to be effective. Common tactics were to climb high so as to have more energy available when you dive and can accelerate quicker, ideally you could attack from up high with your back to the sun and aim to kill the pilot in one burst.

Now ideally you have long range radar pick up enemy fighters on their screens and they use that to vector friendly jets to sneak up on them 50+ miles out with their radars off so they are harder to detect. Then they turn their radars on, fire missiles and if they have superior forces or jets, close to visual range, otherwise they can turn tail and run. The maneuvers are still similar and energy management is still key. High g turns will bleed your speed off (energy) forcing you into wider and wider turns that your opponent can get inside of for a good shot. However the greater range of speed (150 knots to supersonic) means the ability to intentionally slow down as fast as possible could force an opponent behind you to overshoot and quickly turn the tables on him. This tactic was around in WW2 but I haven't heard of it used in WW1.
