In brief: Not supposed to be

The surface is covered with little bumps (filliform papillae) which contain taste buds.
In the back are bigger bulge-y bumps (vallate papillae). A smooth tongue (bald) is an abnormal finding, a sign of (often) nutritional deficiency, e.g. Iron, folate, (folic acid) b vitamin including b12, riboflavin (b2), b6, or niacin. Other causes as well.

In brief: Geographic tongue

You may have geographic tongue, a normal and nonpathologic phenomena where the tongue has many fissure and crack.
It may affect when eat spicy food but it is not a problem and does not need to be concerned.
