Soupers are people who believe in some version of the primordial soup. They believe that life originated in a solution of organic molecules and the most primitive way of getting energy was by oxidizing these molecules. For them, the first biochemical pathways were like glycolysis. Most of them think that complex organic molecules were delivered to Earth by asteroids [see NASA Confusion About the Origin of Life].
Smokers, on the other hand, promote an origin of life scenario that relies on the chemistry surrounding hydrothermal vents on the ocean floor. These environments favor reactions that build up organic molecules from inorganic substrates like hydrogen and carbon dioxide. In this case, the most primitive reactions are simple oxidation-reduction reactions and the most primitive pathways are biosynthesis pathways, not catabolism. This view is often referred to as "metabolism first" [Metabolism First and the Origin of Life].
A reader alerted me to a paper published last year by all the big names in metabolism first [Sousa et al., 2013]. It's an excellent paper. You should read this paper if you really want to learn about modern thinking on the origin of life problem. The biochemistry is complicated but well worth the effort.
I don't have time to explain it all. Here's a teaser ...
At first sight, the idea that chemiosmosis is a very ancient means of energy transduction might seem counterintuitive. More familiar to many is the old (and popular) doctrine that the most ancient pathway of energy metabolism is a fermentation such as glycolysis , an idea that goes back at least to Haldane  and hence arose long before anyone had a clue that biological energy can be harnessed in a manner that does not involve substrate-level phosphorylations and ‘high-energy’ bonds [149,150]. In modern life, all biological energy in the form of ATP comes ultimately from chemiosmotic coupling , the process of charge separation from the inside of the cell to the outside, and the harnessing of that electrochemical gradient via a coupling factor, an ATPase of the rotor–stator-type. It was not until the 1970s that it became generally apparent that Mitchell  was right, his Nobel prize coming in 1978, and it is hard to say when it became clear to microbiologists that all fermentative organisms are derived from chemiosmotic ancestors. We also note that Mitchell's consideration of the problem of the origin of life introduced key concepts of his later chemiosmotic hypothesis, including a definition of life as process, and the idea of vectorial catalysis across a membrane boundary that is inseparable either from the environment or from the organism itself .
The maxim that glycolysis is ancient might be an artefact of experience, since it was the first pathway both to be discovered and that we learned in college; in that sense, it really is the oldest. When one suggests that chemiosmotic coupling in methanogens or acetogens might be ancient, many listeners and readers shy away, mainly because the pathways are unfamiliar and often entail dreaded cofactor names.
