For transposing, get into a word processor and select a monospaced font.

Then type in the following, twice on the same line.

C | C#| D | D#| E | F | F#| G | G#| A | A#| B |

Copy that line to the line below so that you have two of them.
Check that they are really equally spaced, then print them out (on cardstock if you've got it).

Cut the two lines apart and line up the original key signature note with the desired one. Then you can read off all the new chords.
