I think your breakfast is fine.
(Just count the carbs in your vanilla and your splenda - and remember only three sweeteners a day (There usually are sweeteners in protein shakes))
But the soy and the protein shakes are another matter. Even if things are low in carbs they may be high glycemic and therefore affect our bloodsugar. We use the OWL ladder to carefully try out foods to see how we may react to them. On induction we stay with food that are very low glycemic.
It really sounds like you are the kind of person that should start moving up the rungs as soon as your two weeks are over so you can start experiment some. But clean induction is good to eliminate cravings and to get your body adjusted.
