[Grammar] Reported Speech

[amigos]

How can the following sentences be changed in to reported speech?

James said, "Students had started the new lesson when George entered the classroom."

and

He said, "I have been reading a novel since I sat in wheelchair."

My question is, do we also have to change the verb form that comes after the word "since" while changing it into reported speech?

Thanks and appreciated
