The same way as any other two numbers, just remembering that each digit can have the value 0-F, and that carrying from one column to the next is in units of 1016 (= 1610). You may find it easier to convert the numbers to decimal, do the multiplication in decimal and convert the answer back to hexadecimal; or to convert each multiplication to decimal as you do it and convert the answer back to hexadecimal (I tend to do half this way, half directly).
For example:
0x56 x 0x2e: (using long multiplication, writing out each multiplication answer, underscores are used as spaces align the columns)
__2e
__56 X
-----
__54 (0x6 x 0xe = 6 x 14 = 84 = 0x54)
__c0 (0x6 x 0x20)
_460 (0x50 x 0xe)
_a00 (0x50 x 0x20)
-----
_f74
