Honestly, there is so much sugar in those drinks, you'll want a new keyboard/mouse. The keyboards are usually about $30 and the trackpads are around $20. If you're not comfortable replacing them yourself, hire a professional who should be able to do it for an hour of labor $60-$90.
Also, keep it turned off, unplugged, and remove the battery. If some liquid rolls around and gets onto the motherboard things could get a lot worse very quickly.
I don't know which yoga you have, but here are some examples:
If you have some expertise in hardware then dismantle the laptop asap and remove the touchpad and Keyboard connection from the motherboard and dry the laptop out of the coffee you spilled and try putting them back to see if they work. A better thing to do is claim your warranty or repair it for cost or replace the parts. Keyboard dont work after spilling something because their strips will be damages as for the touchpad i am uncertain.
