If it's only for reference, you have complete charts of participles on Smyth §§305-310 pp. 82-85 (pp. 97-100 in the pdf here on textkit
and mostly complete charts of verbs --from the regular to the contracted to mi verbs-- on §§382-422 pp. 112-142 (pp. 127-157 in pdf).
The irregular mi verbs charts are given on §§768-794 pp. 211-218 (pp.226 -233 in pdf).
The pdf pages are very clear and hi-res, and I'm sure printing these pages would cost much less than buying a book for $20, not including shipping.
The reason I like Smyth's charts so much is that everything is clearly laid out: the stem is often separated from the augment, reduplication,
and personal endings; the uncontracted forms are given in parenthesis next to the contracted ones; and if a certain form needs further
explanation, a reference to the relevant section is given.
