In the saddle bag I carry Soma Steel Core tire levers, a Park MTB3.2 multi tool, a small and cheap folding pliers, spare tube; then inside a Altoids tin that also goes in the saddle bag I have a presta to schrader converter, tire boot patch, $40 in cash, ID card, spare batteries for the computer, formerly a glueless patch box used to carry variety of meds just in case, glueless patches, butterfly stitches, and house key (I may be missing some minor stuff).
On the touring bike I have another larger seat bag with all the same stuff as above except more cash, add a VAR nylon tire lever, a spare tire tightly folded and rubber banded together, 3 FiberFix spokes, about 3 feet of duct tape wrapped around the box the spare tube is in, and 4 zip ties.
I carry a pump on both bikes, but I carry an extra pump on the touring bike which goes in a pannier.
I designed the Altoid tin to fit my needs but I got the idea from this:
