​PowerView is a great tool for domain enumeration part of the PowerSploit collection. Almost every function is available in Empire too. Although each function is pretty self-explainable and you should explore it yourself I'll provide some hints here. I can also highly recommend reading the source code for these kinds of Powershell based hacking tools, because there are usually tons of tips and examples bundled with them.

Harmj0y has tips and tricks on his Github too https://gist.github.com/HarmJ0y/184f9822b195c52dd50c379ed3117993​
