IF its not too complex the easiest is to use your biezer tool located 3 down from the top. Jus add a point to every major direction change on your object. (Hint: make your bmp transparent to about 30% and its easy to trace over). Then convert all of you lines to curves and move them around to fit the image.
There is an autotrace feature in corel, but i find it does not work very well. It seems a little tedious to do it the afformentioned way, but with a little practice it should be fairly simple. This also gives you awesome results and will be continually handy in the future.
