On Mondays, most Jews go to school or work, just like everyone else.
If you referring exclusively to religious activities (which are followed exclusively by religious Jews), please refer to the below answer by colleague Dan Galilee.
Monday is a fascinating day of the week for Jews. It is on that day that Jews of all ethnicities,
national origins, and levels of religious observance go to school or to their jobs, watch TV
if they have one, play with their children if any, take food and beverages on one or more
occasions during the day, and in a great number of instances, have social or professional
contact with other people. Very much like most or all of the other days, if truth be told.
Nothing different than any other weekday. Kosher foods.
The only thing in Judaism that makes Monday different from another day is that a portion of the Torah is read on Monday and Thursday morning (in addition to Shabbat).
On Mondays (and Thursdays), the Torah is read during morning services, and the Tachanun prayer is longer than on other days.
