I am going to start my PhD in the next six months and I am not at the level you are questioning about. But I want to answer your question as a person who has seen many professors in the classes. Different classes, different lecturers with different teaching styles. I can understand which way could make me more interested in the person's lessons and which not. Just to say, I am an engineering student.
I think that professors who did only write on the blackboard or just sit behind their laptop and show slides do not attract any attention to themselves or to the things they are teaching. Professor should make connection to the ones sitting in his class. Show that you are a hands on guy. You know every step of the problem you are discussing; not just the theories and nothing else. I have seen the professors who know theories so good, but they are not able to solve a simple example and give their students the final result.
He should walk in the class, but not too much. In a normal way, like the one who is tired of being on his chair and wants to relax.
I love the professors who where not that much restrict in their teaching. Some of them did not pay attention to the questions and just wanted to teach their memorized things. On the contrary, I loved the professors who used to talk to the students. The ones who really think about the thing which is being discussed. The ones who do not think that because they are teaching, they know everything. It is more appreciated that a professor think that when he is in a class, he also can learn many things from discussions and reviewing his notes and slides.
As a professor, I think that it is not a bad thing to say something like you do not have any idea about the solution to a problem. Give the student to show his little knowledge and encourage him to talk among other people who follow the talks.
Giving printed notes, problems or even parts of the lecture to the students is amazing. It encourages even the students who usually sleep at the end of the classroom. At least the bored ones are forced to take a look at the teaching materials and brave students are encouraged to see what more is going to be presented that day.
Make the student feel that you give them freedom in what they are learning. For instance, giving them midterm projects instead of midterm exams may encourage them to work more on their course. Because by doing projects, they feel that they are doing something independently and some applications of their courses; not the exams which may be repeated exactly term by term. Moreover, refer to recent publications and papers during your course. Do not only follow chapters of an old-fashioned book. Show that you follow current researches and know how to apply them to your own courses and projects.
Show that you are accessible in the university or by email. By doing this, you show your students that you care for their problems and questions. I am not interested in the professors that only come to their office once a week and that is the time they have to do their teaching duty.
Pay attention at which level you are teaching, is it a BSc freshman course or is it a PhD coarse. Adjust the level of material you are going to present. High level teaching to the low level student will make them bored. The same applies to the students sitting in a classes that does not add to their knowledge.
Pay attention to your mood (do not be sleepy or tired), Always have smile on your face (but not laugh to everything being said in the class), Do not become angry and wear suitable cloths. Sorry to say that, I have seen some professors who even do not comb their hair.
I think that, if you show that you pay to these little things in your classes; you will have good effect on the assessment group.
