Verse: Asus2-Dsus2-Asus2-Dsus2-Asus2-D-E-G
Chorus: A-E-D-E
Bridge: C#m-B-D-A-E-C#m-B-C#m-D-E
For the most part the A major diatonic and pentatonic scales work here, though the G major chord at the end of the verse incorporates the b7, G - you could either shift to A mixolydian or target the chord tones here, or just be careful to stay away from the G#/major 7th note in the scale.
The bridge modulates to E major/C# minor, though similarly the D major chord is non-diatonic; either avoid the major 7th, D#, switch to E mixolydian here, or look to incorporate D notes in your phrasing. Otherwise, E major/C#m or C# blues work well.
