1. Google the name of the song and the word "chords". Example: from the inside out chords
2. Start clicking links until you get a chart that has all the lyrics and seems to have the chords shown above the lyrics fairly close to where they should be. Do not bother looking at whether any of the chords are in the key you need or if any are correct. Some might be and more than likely, some aren't.
3. Copy and paste into any word processor, or into Planning Center as a chart.
4. Load an mp3 and start playing along. Edit all chords, and lyrics if necessary, as you go along.
I know this isn't an earth-shattering secret, but this works really well for me. I assume the chords I copied are wrong and I'll check every single one, but I'll save time because even though the chords might be wrong, most of the time they are put in the right location.
Another tip you might find useful... if as the band leader you like to do a song very close to the recording, but you modify the chord progression in the bridge, it would be helpful to communicate that to the band. Like with a note on your chart that indicates something like "follow the chord chart for this bridge even though it's different than the recording". It'll save time in the long run.
Got any other tips for creating charts? I'd love to hear them.
