Short of attaching rails to your wood furniture, or swapping your existing furniture for tactical versions with rails, get a barrel flashlight mount, like the following:
Amazon.com: Universal Barrel Mount For 1" Flashlight laser: Sports & Outdoors
For remote operation, the flashlight would need a remote pressure switch. Depending on the taclight model & manufacturer, the remote switch may come with the light, otherwise it is a separate purchase.
And if you intend to game with it at night, don't forget pick up an IR/red filter to minimize blowing your night vision.
