And of course maybe you don't actually want to do any 'figuring', in which case here's a little 'basic' chart that should get you most of the transpositions you are after:

A	D	E(7)	F#m	Bm	C#m
C	F	G(7)	Am	Dm	Em
D	G	A(7)	Bm	Em	F#m
E	A	B(7)	C#m	F#m	G#m
F	Bb	C(7)	Dm	Gm	Am
G	C	D(7)	Em	Am	Bm

Of course a capo is a simpler solution, here's a capo table to tell you where to put it to play in any key with any chord shape you prefer:

Key played	Base chord shape to use
	A	C	D	E	F	G
A	0	9	7	5	4	2
Bb	1	10	8	6	5	3
B	2	11	9	7	6	4
C	3	0	10	8	7	5
C#	4	1	11	9	8	6
D	5	2	0	10	9	7
D#	6	3	1	11	10	8
E	7	4	2	0	11	9
F	8	5	3	1	0	10
F#	9	6	4	2	1	11
G	10	7	5	3	2	0
G#	11	8	6	4	3	1
