Be sure to grease your pan to make it easy to remove the baked banana bread, and allow it to cool in the pan for about 20 minutes before trying to remove. Use a butter knife to loosen the bread around the edges of the pan. Place a wire rack or your hand over the top of the bread, then invert the pan, giving it a little shake if it sticks. The bread should slide out easily. If not, scrape around the edges with the knife again, or use a metal spatula to try get to the bottom. You could also cut out one slice, then use the extra space to get a spatula under the bread to help loosen the bottom.
