I suppose you want to land your stage on the launchpad or something like that?
@GuHP20 is right, sadly I can't really help for that. And even if I could it wouldn't be simple: drag is a very difficult force to deal with.
However, I can advise you on how to land without using too much fuel. My favourite trick consists in adding structure on the upper part of the rocket: they generate a lot of drag. By making the upper part more resistive, your rocket will point naturally upwards during the reentry. That way you won't rage and waste fuel to try maintaining the orientation of your launcher as desired. You can enclose them into fairings first, so that they don't harm you for the lift off.
Then, during reentry, never turn on the engines, let the drag make that work for you. The atmospheric pressure is maximal close to the ground level, so don't worry, your rocket will slow down.
Then all you have to do is turning on the engine to control the last meters of the descent. You'll only have to burn at part throttle during a few seconds, so this really needs very little fuel.
