It's fairly simple to do:

You will need to Source a starter button, make sure its able to handle the amps going to be passed through it. The "Starter" buttons are pretty beefy, so you may want to opt for a Late model start button and a relay setup. Wire the button to the small starter wire.

You will need toggles for Ignition, Acc., and Fuel pump if your running an electric unit. You will want to hook the Accessory switch to a buss bar to feed your lights, radio, fan, ect.. This will prevent you from having 5 feeds off the toggle.

Ignition switch will be wired to the power wire on the distributer.

Once everything powers up from switches, you start the truck by powering up fuel circuit, power up Ignition, and press the start button. I find that spinning the motor over and then turning the ignition on will make the engine fire quicker with less opportunity for the engine to snap back and flood.

Hope this helps, I run the ignition for my street/strip car this way, but still use the key to power up the switches to keep my car MINE!
