First off, you're gonna have to put in some work.
First things first, just be quick and agile. While speed on the court and the etc is important, I'm going to assume you already have that.
In terms of layups, come in at an angle. Take two steps once inside the 3 point line, and jump off your foot closest to the hoop. To "layup" the ball, don't shoot it, just place the ball, making it go off the top corner relative to the side you're on, making it go in. This video is pretty good.

Dribbling is a very important aspect. I guess if you wanna just play to win a fun little match, you don't have to go crazy with a bunch of moves, but just be solid.

In terms of shooting, everyone is different. Just do what works for you, and you'll likely be fine. If you have no idea what to do, this guy explains pretty well the proper form.

Now I didn't cover a lot, but If you have these fundamentals, you should be just fine.Sry if I linked a bunch of vids, but bball is hard to explain via text.
