Hi David, plan according to the time and the size of the group. The areas to train would normally start from basic English sounds/phonemes (for this, teach your trainees the IPA chart if you can), then minimal pair sounds (short and long sounds, for instance). Focus on the sounds we Indians generally have problems with (v and b, th, schwa, diphthongs, etc.), and give them loads of practical exercises including jaw and vocal exercises, breathing, tongue twisters, poems, word and sentence stress, and intonation.
My accent neutralization/modification training is usually for 30 hours, and I chunk the above to fit this. But you can choose the most important areas keeping the needs of your trainees in mind. They will need to HEAR before they can speak and practice English sounds, rhythm, stress, and intonation.
It is a real gift to give them the IPA chart because once they've learned it, it is theirs for life. Since it is impossible to teach pronunciation of all words, if they learn the phonemic alphabet, they can look up the pronunciation of any word they wish. The most important thing is to make them self-reliant and confident, and a large part of this is enabling them to use the dictionary to look up the pronunciation of any given word. Remember, the very first piece of information in a dictionary after the word is its pronunciation, and it is a pity so many of us are unable to get this.
Good luck and hope you enjoy the training.
