Hey Barbra,
In addition to the suggestions provided, if you check out the improved Family Search web sites which in addition to a much more robust search capability, have added some learning and sharing (via wiki format) features. The learning venue offers courses on handwritten records and there are 3 lessons on reading French handwritten vital records. Although the quest for a "template" will remain illusive, there was a general methodology to the way these records where created wrt the sequence and type of information recorded for baptisms, marriages, and burials that was followed across 300 years. (Despite a formal education system, all trades were taught as apprenticeships with skills handed down generation to generation...this included church clergy and clerks.)
These interactive videos are very well done and worth your time. See
