Hi Fiona
As far as I'm aware, as yet there is no NBI for Scotland though I beleive that is an eventual aim - "The Scottish National Death and Burial Index" is a project which has been undertaken by S.A.F.H.S. with the member societies and the G.R.O. for Scotland. So many local FHS are involved in collating MIs & burial information for their own area just now.
We have a list of web sites which may of some help here (being added to all the time!);

and the largest depository of published and unpublished MIs in Scotland is held by the Scottish Genealogy Society:
www.scotsgenealogy.com
They also sell MI books through their online shop, and I can see there is a publication which covers Kilsyth:

Publications for the other areas you are interested in can be found here:

Local libraries may be able to help with specific look ups if they have the publications - see library link at top of page.
More info about MIs in general can be found here:

The other area to explore is to find out if any death records exist in the OPRs for the area you are interested in. A pdf file from the GROS site should help you with this. If you find some death records do exist you could order the microfilm from your local LDS Family History Centre for a small fee. However, death, burial or mortcloth records in OPRs can give very sparse information in most cases - it is a lucky & reasonably rare find which includes name, age & cause & date of death! Depends on the parish.

Lastly, there may exist some lair records for the areas you are interested in. Usually this would involve contacting the local council, or sometimes the local crematorium & they may be able to give some further information, though often a date & place of death is required before they can help & some area charge a fee for this service.
Hope all this is of some help. I've not looked yet at the individual areas you mentioned, but if you need any further help or info, just yell!
Best wishes
