You mean Mirror the iPad to the Mac?
While there is no Mirroring app specifically for the iPad, like there is for the iPhone, you can still see the iPad's screen on the Mac by enabling the AirPlay receiver function, and then use AirPlay option in the iPad to mirror the screen to the Mac.
On the Mac go to System Settings ➜ General ➜ AirDrop & Handoff ➜ AirPlay Receiver and make sure it's turned on.
Then on the iPad, open Control Center, tap on
(the Screen Mirroring icon), and then look for your Mac in the list there. Tap it, and your iPad's screen should appear on the Mac.
You'll still need to control it using the iPad though.
