One of the quickest ways to get the fire burning is through Kaphalabhati. Take a comfortable seat and close your eyes. Touch the forefinger and thumb together on each hand. Inhale through your nose and quickly exhale through your nose, as you draw your belly back toward your spine. The inhale is passive and the exhale is sharp and quick. You can go fast or slow according to your comfort and do as many rounds as you like.

Set Your Manipura Intention
Now set your intention for this practice. To grease the wheels, here are some themes that relate to the third chakra: My happiness depends on no external source; I release all blame and transform that into freedom to create the life that I want; I am worthy and inherently powerful; I can contribute to the world in a meaningful way; where can I release shame, self-critical, or over controlling thoughts/actions? Feel free to use any of those or choose your own. As long as your intention feels true for you it has value.
