This is a simple case of dominant, pack leader behavior. Cats are very much like dogs as in they are pack oriented and look to or become pack leaders. You need to establish this position by relating to her in cat terms. Cats communicate vocally and physically, different sounds and body positions as well as movements suggest different commands. For instance hissing often gets their attention, clicking, whistling, snapping your fingers or clapping your hands. Any command needs to be communicated before the actual action, when it is first realized. As soon as she looks at your dish or if you walk into kitchen and she follows, walk out paying no mind to her. This way you are disassociating kitchen with food.
Maia loves food, she is a perfect little lady when it comes to me eating, but loves to beg for her food. I have to regulate her feeding to watch her weight, but she respects me and my plate, in return I always allow her to smell or lick the plate. Picking them up and putting them else where isn't asking for respect, it is gibing them attention for that behavior which only encourages it. You need to deter the action before hand, keep her at a distance through vocal or physical command prior to.
