Is there a good way to hook a keyboard from a macbook or iOS device to an apple tv?

You need to download the remote app from the App Store. After installed, you'll be able to use your iPhone or iPad as a remote.

I just bought an Apple TV. How can I pair either my laptop or iOS device to the Apple TV to use its keyboard.

You can't pair a physical keyboard. Look at the suggestion above.

you can go to the settings pane in the apple tv and pair a bluetooth keyboard. to read more about this, click here: http://support.apple.com/kb/HT5633

And, I had also forgotten that there is a app called Type2Phone so you can use your mac's keyboard as a apple tv keyboard.
