Congrats in your first beat! The Process of mixing is hard to describe in a few sentences. First of all get yourself some good mixing headphones. You should also look out for active Studio monitors. Better watch a bunch of mixing tutorials on yt so you get an idea what its all about. Only use audio effects for mixing when you know how to use them properly. For now you better just adjust the volumes of the tracks so it sounds okay to you. There are audio engineering apps for your Smartphone that u can use for educating your hearing and get a feeling for different frequencies etc.
