A teaching portfolio contain samples of your teaching performance--artifacts and examples. Work samples are usually accompanies by faculty commentary and explanation that reveals not only what was done but why, the thinking behind the teaching. Reflective essays that demonstrate a teaching philosophy ground the portfolio by giving it a point of view.
Portfolios are constructed in many ways; there is no set structure. But keep in mind their purpose--to reveal your effectiveness as a teacher, your competency as a planner, your involvement in the field, and your contributions to your professional community.
