The liver produces insulin-like growth factor 1 (IGF-1), which is involved in growth; it is secreted in response to growth hormone stimulation.
The liver also makes angiotensinogen (not angiotensin...remember, angiotensinogen is cleaved in the blood to form angiotensin I by the action of renin, which is released by the kidneys). I'm not sure if angiotensinogen can be considered a hormone though.
The only other hormone that I can think of that is produced in the liver is thrombopoietin, which is used to regulate platelet production by the bone marrow.
Maybe others know of other hormones produced by the liver. I don't think you need to know which hormones are produced by the liver for the MCAT though (you might need to know IGF-1 and you most likely need to know about angiotensinogen but I have doubts about thrombopoietin and any others); I can see the hypothalamic and pituitary hormones being the important ones to know (in addition to what hormones are released in response to these).
