Smoked Salmon on the grill

Using a grill with a cover has its advantages over cooking on an open fire when it comes to smoking. At home I use a grill, when camping an open fire. With the grill if you use wood planks get the planks hot first like a frying pan put olive oil on top then add fish. By then the wood has dried out some and the edges begin to burn and add smoke flavor to the fish when the wood gets hot the oils from the wood infuse into the fish also giving it flavor. I have tried wood chips in a can but as someone else posted the fish will be done before the wood chips smoke.
