The double treat method works well.
My most recent success has been with ham lunchmeat sliced as thin as they can slice it at the deli. I roll the pill in a small pc and have the second piece there to offer as soon as she has the pill loaded one in her mouth. If you have a second dog, they help with the competition factor.
I've also used bread wrapped around a pill and dipped in a dab of pizza sauce.
Some pills are made for time release and should not be crushed up. But if you check with your vet and it can be crushed, you can try crushing the pill. I keep a recipe card handy, folded in half. Crush the pill into a fine powder with a marble pestle. Put the powder on the card. Get an oral syringe and use the folded card like a funnel to get the powder in the syringe. Add just a little water and shake it up good. Then squirt it into the side of their mouth.
