WHAT IS THE BEST WAY TO VENT SMOKE THRU A GARAGE WALL?

As you can see by the previous post below this one, many of us use 5 inch heat duct pipe when outdoors. However, in your case I would use double wall chimney pipe, the kind used on gas and wood burning stoves. The reason being:
1) It's made to go though walls and keep the heat away from combustibles.
2) There are flanges and seals built for this pipe to keep weather and insects out of the wall.
3) Just incase you do have a fire you're not going to melt the pipe and burn your house down.
The only heat we had in the backwoods house I grew up in Washington was what we cut and burned in our cast iron wood stove. Chimney fires were always a threat so I grew up sleeping with my eyes closed and my nose awake. If you really want to go all the way, check into the commercial installation instructions that are available from Cookshack.

If your garage has a window, I'd get a piece of plywood to close the window down on, cut a hole and vent through it. Then if you decide to move sometime in the future, you don't have a hole in your wall to fix.
That is what I did, but I used a piece of cement board instead of plywood to keep the combustibles away from the pipe
I forgot to mention. At the bottom of the elbow drill a small hole weep for grease to drip out. Grease will build up inside of vent pipe and when warm, run down and out cracks in pipe. I then put an out milk jug with the top cut off (half full of water) under the drip. If you've got animals around that are looking for BBQ, add some vinegar to discourage their taste buds.
