A 2 5 1 in A would be Bm7 E7 Amaj7 which would finish the tune for you. You could swap the Amaj7 for A69,

Also
3 6 2 5 1 would work, C#m7 F#m7 Bm7 E7 Amaj7, once again the final chord could be A6 or A69,

In both examples the chords could be one or two per bar it all depends on how you here the song and style as well
